Knurled point 18-8 stainless steel socket set screws are headless threaded fasteners designed to secure collars, hubs, gears, pulleys, couplings, sprockets, knobs, handles, and other shaft-mounted components. The internal hex drive allows installation where external wrench clearance is limited, while the serrated knurled point is designed to increase contact with the mating surface for applications requiring dependable holding characteristics. Their compact design allows installation flush with or below the surrounding surface.
Manufactured from 18-8 stainless steel, these socket set screws provide general corrosion resistance for many industrial environments exposed to moisture, humidity, or routine washdown. They are commonly specified for machinery, automation equipment, conveyors, power transmission systems, instrumentation, maintenance repairs, food processing equipment, and OEM manufacturing where stainless steel construction is preferred.
Knurled point geometry is commonly selected where increased contact with the mating surface is desired. Depending on the shaft material and installation conditions, the serrated point may leave a witness mark on the contacted surface. Proper fastener selection should consider thread size, screw length, hex socket size, mating material, installation access, acceptable surface marking, and service conditions. Individual product pages provide verified engineering dimensions to assist engineers and purchasing professionals in selecting the appropriate fastener.
Cold Headers supplies knurled point 18-8 stainless steel socket set screws in a broad range of inch thread sizes and lengths, including standard, uncommon, and difficult-to-source configurations. Our catalog is organized to simplify exact-size sourcing while providing consistent engineering information across every product family.
Begin by confirming the required thread size and screw length. Review the hex socket size, mating material, installation clearance, operating environment, acceptable surface marking, and assembly requirements before selecting a fastener. Knurled point socket set screws should not be substituted automatically for cup point, cone point, flat point, oval point, half dog point, or full dog point designs because each point geometry serves a different mechanical function.
Cold Headers Inc. has supplied specialty industrial socket fasteners since 1962. Our catalog helps engineers, distributors, maintenance professionals, and purchasing teams locate exact sizes, uncommon lengths, and difficult-to-find knurled point socket set screws without unsupported inventory claims.
